The cartridge shell may also be provided with no partly pierced or weakened zones 12, so that the planter may completely pierce the same, to increase the outlets for the initial discharge of the fertilizing material.

The moisture of the ground is slowly absorbed by the cartridge shell and moisture penetrates through its many openings, soas to dissolve the fertilizing material, which more readily exudes through the openings of the shell.

The wrapper 11, shown in Fig. 2 is intended to protect the cartridge, while it is under sale to the ultimate user, but the inner wrapper 11a may be made of softer paper or material, which will more readily disintegrate, and which may be left on the cartridge, when it is desired to delay the process of soil absorption of the fertilizing material orother plant or tree food used.

The inner wrapper may also consist of a series of overlapping sections 11b, shown in Fig. 5, so that one or more of these sections may be removed, so that all of the perforated area of the tubular shell will not be exposed, and delayed absorption may be obtained in this way.

In Fig. 6 I show a cartridge, constructed with a perforated tubular shell 13 and the end closures or caps 14 and- 15, which is provided with a charge of benzine crystals or other exterminating material. This cartridge is used for killing moles and similar ground parasites. This cartridge is inserted in a hole formed in the soil, which is then filled in, so that the ground will absorb the material, and any animal life coming in the zone thus treated will be killed.

Before the cartridge is inserted in the ground, it is dipped in water and then dropped in the hole prepared to receive it. Water is supplied to the soil around the hole at least once a week, in order to keep the plant food or fertilizing material in the best condition.

Having described my invention I claim as new:

A fertilizing cartridge, consisting of a shell having a plurality of outlets formed in the same, a charge of fertilizing material in the shell, and wads of moisture holding moss in the shell.
